I've got this strange idea... Wouldn't it be great if companies decided to bundle a smartphone and a tablet in a single package, which could help reduce the cost and electronic waste?
For example, a hypothetical Apple package would contain:
iPad with Retina Display
iPhone 5
Lightning to USB Cable
USB Power Adapter
Apple EarPods with Remote and Mic
For a diverse ecosystem like Samsung, this works even better... USB connector, Power Adapter, a microSD Card and a stylus would suffice, assuming the package contains a Galaxy Note 2 and a Galaxy Note 8.0.
Though the cost benefits may not be huge, it could help reduce the problem of electronic waste. Customer gets cost benefit and the manufacturer gets the customer hitched to their eco system.
Isn't it a win-win situation for both?
